Integral Sign Galaxy (UGC 3697)

The Integral Sign Galaxy (UGC 3697) is a very thin, faint, edge-on spiral galaxy in the constellation Camelopardalis. Its distinctive
shape helps dispel any notion that there's no link between astronomy an
mathematics! The Integral Sign Galaxy (Uppsala 3697) is an example of a
"super-thin galaxy" – a term devised by Goad and Roberts in the 1980
for edge-on galaxies with with an axial ratio of 8:1 or more, and other
peculiarities such as a lack of central bulge. Just 8' SE (perhaps 39 kpc
in linear distance) lies another a bright galaxy, gravitational interaction
with which might be the cause of the Integral Sign's warped-disk.
